The present disclosure relates to a cable, and in particular, to a cable assembly and a cable indication system with controllable settings.

DISCUSSION OF THE BACKGROUND

Cable assemblies with fiber optic cables are used in various environments for power and data transmission between different devices. These environments are often cluttered by large quantities of the cable assemblies. Moreover, the operator often needs to quickly identify different devices among the cluttered arrangement of the cables. The cluttered arrangement of cables often leads to decreased efficiency and aesthetics of the environment. Often, the operator introduces more clutter in trying to organize the cables. Minimizing the clutter of the cable assemblies with intuitive and controllable identification while maintaining aesthetics has become crucial in gaining or network environments.
